ISRO का शुक्रयान-1 मिशन: शुक्र ग्रह के रहस्यों को सुलझाने की तैयारी
भारतीय अंतरिक्ष अनुसंधान संगठन (ISRO) ने अपने आगामी शुक्र मिशन 'शुक्रयान-1' के लिए नए पेलोड और लॉन्च तिथि की घोषणा की है।
2-Minute Summary (TL;DR)
- ISRO's Shukrayaan-1 mission to Venus is targeted for launch in December 2026 or early 2027.
- The mission will carry advanced payloads including a 12-band multispectral camera, Synthetic Aperture Radar (SAR), and Ground Penetrating Radar (GPR).
- SAR will enable mapping of Venus's surface through its dense cloud cover.
- Key objectives include studying Venus's atmosphere, surface geology, and interaction with solar winds.
- Understanding Venus's runaway greenhouse effect can provide insights into Earth's climate change.
- Shukrayaan-1 aims to place India among the elite group of nations that have studied Venus.
- The mission builds upon ISRO's successful Chandrayaan and Mangalyaan interplanetary missions.
- The mission duration is expected to be at least four Earth years in Venus orbit.
- Studying Venus helps in comparative planetology, understanding planetary evolution and habitability.

Practice Questions
Q1. What is the revised target launch window for ISRO's Shukrayaan-1 mission?
- December 2024
- Mid-2025
- December 2026 or early 2027
- 2028
Explanation: ISRO has officially announced that the launch of Shukrayaan-1 is now planned for December 2026 or early 2027. This revised timeline allows for further technological advancements and optimal mission planning.
Q2. Which of the following instruments is designed to map Venus's surface through its thick clouds on the Shukrayaan-1 mission?
- 12-band multispectral camera
- Synthetic Aperture Radar (SAR)
- Ground Penetrating Radar (GPR)
- Magnetometer
Explanation: The Synthetic Aperture Radar (SAR) is a key instrument on Shukrayaan-1 specifically equipped to penetrate Venus's opaque atmosphere and provide high-resolution images of its surface topography.
Q3. What is a primary scientific reason for studying Venus's extreme greenhouse effect?
- To find evidence of past life
- To understand potential resource extraction
- To gain insights into Earth's climate change dynamics
- To study the formation of sulfuric acid clouds
Explanation: Venus possesses a runaway greenhouse effect, making it extremely hot. Studying this phenomenon helps scientists understand the mechanisms and potential consequences of extreme greenhouse effects, offering valuable lessons for managing climate change on Earth.
Q4. Besides Shukrayaan-1, which previous ISRO missions have successfully explored other celestial bodies?
- Aditya-L1 and Chandrayaan-2
- Chandrayaan missions and Mangalyaan
- Gaganyaan and Chandrayaan-3
- Mangalyaan and Aditya-L1
Explanation: ISRO has a proven track record with interplanetary missions, notably the Chandrayaan program which explored the Moon and the Mangalyaan mission which successfully reached Mars.
Q5. What is the significance of Shukrayaan-1 in terms of international space exploration achievements?
- It will be the first mission to land on Venus.
- It aims to establish a permanent base on Venus.
- It will place India among a select group of nations that have studied Venus.
- It is a joint mission primarily led by NASA.
Explanation: Successfully executing the Shukrayaan-1 mission will add India to the list of countries like the USA, ESA, and Russia that have conducted dedicated missions to Venus, highlighting ISRO's growing capabilities in complex space exploration.
How to Prepare Science & Technology for Government Exams — ISRO का शुक्रयान-1 मिशन: शुक्र ग्रह के रहस्यों को…
For Railway exams, make flashcards for every major ISRO launch — name, payload, purpose, date. These repeat frequently.
For SSC, focus on defence acquisitions and their strategic significance rather than technical specs.
For UPSC, connect every scientific development to policy — climate targets, digital India, health policy.
